steps

Sew fabric pieces together along 12-, 24-, or 42-inch side, pressing seam toward darker side (which will be bin interior).

Fold work in half and sew along long side, leaving a 3-, 4-, or 6-inch gap in darker side and creating a tube.

Position tube so seam is down center; press seam open. Sew short ends closed.

Reach hand into seam gap and turn work right-side out. Push with fingers to sharpen corners.

Tuck lighter side (which will be bin exterior) into darker side. Hand-sew gap closed with a blind stitch.

Fold bottom corner point over 1, 2 1/2, or 5 inches, making sure corners are smooth. With tailors’ chalk, mark fold line. Pin in place through all layers of fabric. Sew along chalk lines. Repeat with other corner. Turn lighter-fabric-side out; fold over rim as desired.
